PURPOSE: To investigate the possible factors involved in the development of acute hydrops in patients with keratoconus. DESIGN: Prospective interventional case series. METHODS: Thirteen consecutive keratoconic eyes of 13 patients with acute hydrops were examined by ultrasound biomicroscopy (UBM). RESULTS: Ultrasound biomicroscopy (UBM) examinations revealed a rupture of Descemet membrane and intrastromal clefts in all eyes. In 11 of 13 eyes, the intrastromal clefts were connected to the anterior chamber. CONCLUSIONS: Formation of intrastromal clefts may be an important factor in the development of acute hydrops in keratoconic eyes. The clefts may cause severe corneal edema and delay the closure of Descemet membrane during the resolution of corneal edema.
